FIELD OF THE INVENTION

The present invention is generally related to an agricultural formulation comprising 3-(difluoromethyl)-1-methyl-N-[(3R)-1,1,3-trimethyl-2,3-dihydroinden-4-yl]pyrazole-4-carboxamide and sodium salt of naphthalene sulfonate condensate and polyoxyethylene tristyrylphenol phosphate, potassium salt. The present invention is further related to an agricultural formulation comprising 3-(difluoromethyl)-1-methyl-N-[(3R)-1,1,3-trimethyl-2,3-dihydroinden-4-yl]pyrazole-4-carboxamide, ethaboxam, metalaxyl, mandestrobin, methyloxirane polymer, sodium salt of naphthalene sulfonate condensate, a mixture of sodium salt of alkyl vinyl ether/maleic acid half-ester copolymer and polyvinyl pyrrolidone and polyoxyethylene tristyrylphenol phosphate, potassium salt. The present invention is further directed to a process for preparing the agricultural formulations and methods of use thereof.

BACKGROUND OF THE INVENTION

Fungal infections are a major concern for crop growers. Fungi can be present on the seed surface prior to planting, they can be soil-borne, or they can be introduced into the growing environment by mobile pests or equipment. Fungi infect seeds and seedlings and destroy plant cells and tissues and thereby prevent seed germination or cause poor development or death of seedlings. Aphanomyces, Fusarium, Helminthosporium, Pythium, and Rhizoctonia are all known to cause infection and death of plants. These organisms cause seed rot, damping-off, seed blight, and root rot. Even diseases that affect adult plants can be controlled by pesticidal seed treatments (e.g., smuts caused by Ustilago, Tilletia, and Urocystis).

Metalaxyl is a widely used fungicide for controlling diseases among crops. Metalaxyl is the active ingredient in the seed treatment marketed as Sebring® 318 FS (Sebring is a registered trademark of and available from Nufarm Americas Inc) and Allegiance® FL. However, metalaxyl presents many formulations challenges including its low melting point (63-72° C.) and partial water solubility (8,400 parts per million). Liquid formulations of metalaxyl often form large crystals upon storage. Further, due to its low melting point, formulating metalaxyl with other low-melting point pesticides is highly problematic. To date there is no known finely milled aqueous slurry of metalaxyl and another low-melting point pesticide.

Inpyrfluxam (i.e. S-2399; 3-(difluoromethyl)-1-methyl-N-[(3R)-1,1,3-trimethyl-2,3-dihydroinden-4-yl]pyrazole-4-carboxamide) is a novel succinate dehydrogenase inhibitor fungicide. Inpyrfluxam presents many formulations challenges including its low co-melting point with metalaxyl (less than 50° C.) and crystal formation in liquid formulations upon storage.

There remains a need in the art for physically and chemically stable formulations containing inpyrfluxam and other low-melting point pesticides useful for seed treatment that provides improved protection against fungal pests. Further, there is a need in the art for a process to prepare such physically and chemically stable formulations containing inpyrfluxam and other low-melting point pesticides.

DETAILED DESCRIPTION OF THE INVENTION

Milling 3-(difluoromethyl)-1-methyl-N-[(3R)-1,1,3-trimethyl-2,3-dihydroinden-4-yl]pyrazole-4-carboxamide, ethaboxam, metalaxyl and mandestrobin together causes crystal growth. Applicant unexpectedly found that formulating 3-(difluoromethyl)-1-methyl-N-[(3R)-1,1,3-trimethyl-2,3-dihydroinden-4-yl]pyrazole-4-carboxamide separate from a formulation containing ethaboxam, metalaxyl and mandestrobin and the mixing the two formulations provide a physically stable formulation. Specifically, the Applicant has unexpectedly discovered a stable agricultural formulation comprising 3-(difluoromethyl)-1-methyl-N-[(3R)-1,1,3-trimethyl-2,3-dihydroinden-4-yl]pyrazole-4-carboxamide and sodium salt of naphthalene sulfonate condensate and polyoxyethylene tristyrylphenol phosphate, potassium salt. The Applicant has further discovered a stable agricultural formulation comprising 3-(difluoromethyl)-1-methyl-N-[(3R)-1,1,3-trimethyl-2,3-dihydroinden-4-yl]pyrazole-4-carboxamide, ethaboxam, metalaxyl, mandestrobin, methyloxirane polymer, sodium salt of naphthalene sulfonate condensate, a mixture of sodium salt of alkyl vinyl ether/maleic acid half-ester copolymer and polyvinyl pyrrolidone and polyoxyethylene tristyrylphenol phosphate, potassium salt. The Applicant has further discovered a process by which these agricultural formulations can be made. A stable agricultural formulation comprising 3-(difluoromethyl)-1-methyl-N-[(3R)-1,1,3-trimethyl-2,3-dihydroinden-4-yl]pyrazole-4-carboxamide is unexpected because crystal and/or particle size growth normally occurs with this compound. A stable agricultural formulation comprising 3-(difluoromethyl)-1-methyl-N-[(3R)-1,1,3-trimethyl-2,3-dihydroinden-4-yl]pyrazole-4-carboxamide, ethaboxam, metalaxyl and mandestrobin is unexpected because of the co-melting that occurs between 3-(difluoromethyl)-1-methyl-N-[(3R)-1,1,3-trimethyl-2,3-dihydroinden-4-yl]pyrazole-4-carboxamide, metalaxyl and other actives. As previously mentioned, stable formulations containing 3-(difluoromethyl)-1-methyl-N-[(3R)-1,1,3-trimethyl-2,3-dihydroinden-4-yl]pyrazole-4-carboxamide or metalaxyl are difficult to obtain because undesirable crystals form.

In another embodiment, the present invention is further directed to a method of protecting plants comprising treating plant propagation material with a fungicidally effective amount of an agricultural formulation of the present invention.

In another embodiment, the present invention is further directed to a method for controlling or preventing pest damage of plants comprising applying to the plant propagation material an effective amount of an agricultural formulation of the present invention onto a plant propagation material.

As used herein, “plant propagation material” refers to seeds, bulbs, rhizomes and tubers.

In a preferred embodiment, the plant propagation material is a seed. In a more preferred embodiment, the formulations of the present invention are applied to the seeds before they are planted.

In another preferred embodiment, the plant that is treated is a crop plant. In a more preferred embodiment, the crop plant is selected from the group consisting of corn, soybeans, beans, peas, lentils, flax, wheat, rice, canola, sorghum, barley, oats, rye, millet and sugar beets.

The phrase “effective amount” of the formulation means a sufficient amount of the formulation to provide the desired effect. In general, the formulation is employed in amounts that do not inhibit germination of the seeds (or cause phytotoxic damage to the seeds) while providing adequate pest control. Pest control can mean reducing pest damage to the plant, reducing the amount of pests on the plant or in its immediate environment, or preventing the pests from reproducing, among other things. The amount of the formulation may vary depending on specific crops and other factors. It is well within the ordinary skill in the art to determine the necessary amount of the formulation.

As used herein, “pest” refers to pathogens and parasites that negatively affect the host plants by colonizing, attacking, irritating, or feeding upon them, or competing for nutrients with the host. A pest may be, for example, an undesirable bacterium, fungus including fungal pathogens, or insect.

Fungal pathogens include but are not limited to Rhizoctonia, Fusarium, Pythium Phytophthora, Phomopsis, and seed decay fungi including Aspergillus, Penicillium, Alternaria, Rhizopus, and Basidiomycete bunt and smut fungi.

As used herein, “plant” and “plants” refer to wild type and genetically modified members of the plant kingdom, including higher (vascular) plants and lower (non-vascular) plants.

As used herein, “crop plants” refers to cereal, legumes, forage crops, stem and leaf crops, tuber, bulb and root crops, fruit and seed vegetables, fruit and nut crops, beverage crops, oil, fat and wax crops, spices, perfumes and flavorings, and ornamentals, forest and fiber crops.

The formulations of the present invention may be applied simultaneous or sequentially to the areas in need of treatment.

The formulations of the present invention can be applied to any environment in need of pest control. The environment in need of pest control may include any area that is desired to have a reduced number of pests or to be free of pests. For example, the pesticide can be applied to areas where crop plants are grown.

As used herein, “controlling or preventing pest damage in a growing plant” refers to maintaining the population of the target pest at a rate per plant such that the plant is viable and produces an agriculturally useful product.

As used herein, all numerical values relating to amounts, weights, and the like, that are defined as “about” each particular value is plus or minus 10%. For example, the phrase “about 10% w/w” is to be understood as “9% w/w to 11% w/w.” Therefore, amounts within 10% of the claimed value are encompassed by the scope of the claims.

As used herein “% w/w” and “percent w/w” refer to the percent weight of the total formulation.

The disclosed embodiments are simply exemplary embodiments of the inventive concepts disclosed herein and should not be considered as limiting, unless the claims expressly state otherwise.

The following examples are intended to illustrate the present invention and to teach one of ordinary skill in the art how to use the formulations of the invention. They are not intended to be limiting in any way.
